Question about 1991 Yamaha FZ 750 KS (Europe)

1 Answer

Chaine question i! put 'er in gear and and shifts just fine. Though I didnt ride too much as no headalight and no helmet yet. I have a question about the drive chain tho. I had the rear wheel in the air, and put the bike in gear... and the bottom of the chain kicked and oscillated a little bit too much.. approx 2-3 cm. Now if I raise the throttle slowly the chain does not kick, but on releasing it it does so again. This is of course all with the rear wheel in the air. So am I just freaking out, or is thihs just because there is no load on the engine, or do I need a new chain??? Also, I hear the slight buzz of the cam chain when Im close to the engine. What is the noise level for a cam chain??

The chain will flop around when running it on the center stand.the chain should have from 5/8 to 1 inch of slack in the middle of the chain when on center stand on the bottom run of the chain. if you adjust it turn the chain to find the tightest place in it and then adjust it at that point.if you adjust it at the loosest point it will be too tight--they dont wear even.dont know about cam chain noise--i wouldnt worry about it they dont give much trouble.

1998 CR125. Why won't it hit 4th?


Chain adjusted correctly? (i know it sounds silly, but it did effect a Bike i had).
Was it the correct weight oil? Thicker oil means harder to change.
Personally, i prefer to listen>test ride to determine an issue.
Good Luck with it, i'd love to know how you get on.
In the meantime...YouTube/CrashTestDummyTV.
Cheers n 'Happy Trails'...soon 4u i hope.

There is a tic-toc noise coming from my bike as I accelerate. Chain and sprockets are fine. Is this my shifting cam?


The shift drum would not make any noise, ever. The drum will outlast all of us. All it does is move clockwise and counterclockwise as the rider pushes the shift lever up or down as needed. Go to an empty parking lot or roadway and start out slowly in 1st gear, slowly gaining speed. Does the knock show up? Now go into 2nd gear and slowly gain speed. Is the knock there? Do the same for all the gears. If the knock is only in one or two gears the problem is a broken gear tooth. When the broken gear is replaced, also replace any other gear the broken gear meshes with. Whatever broke the tooth also put the same pressure on the meshing tooth. If the meshing gears are not replaced you will have the pleasure, ( and expense ), of doing the repair all over again when the cracked tooth on a meshing gear decides to break off. This usually happens within the first hour of riding the "fixed" bike. If the test shows no knock in the gears, then chances are the knock is a cam chain needing to be tightened. Please rate my answer. Thanks. tombones49_175.gif

I have a 2000 dyna low rider,the backing plate for the chain adjuster came lose after reseting the screws,engine runs gratebut if i put it in to any gear it does not move,, but also seems hard to get in to...


I had asked for clarification on the "does not move", and said you may have parts from the tensioner between the chain and sprockets. Sorry, this cannot be, since you said the engine runs fine. Again, sorry. Does your transmission clunk or grind when going into gear? OR, does it not make any noise at all when putting it in gear? You say hard to get in gear when you shift? I think I need some more info to help you with this.

While riding the transmission shifts uncommanded and clicking noi


Assuming the drive chain and sprockets are in good condition.(check these first)
This sounds like and internal gearbox problem, a bearing has collapsed or a tooth has broken of a gear.
Riding it like this will cause more damage. The gear box will likely need to be stripped

2003 SUZUKI GSXR 600 SHIFTING QUESTION


just input , not resolving anything. but i used to have a similar issue with mine, but i had a gs 750t . it has around 20,000 on the clock. sometimes it didnt want to shift into 1st from a dead stop, i had to let out on clutch, then pull clutch again , then it went right in. the gears are so fine cut in the bikes that once they get worn, even the shift fork, it gets a little harder to get into those gears without a little coaxing. by the sounds of it (without knowing the mileage) i dont think id worry too much. especially if its shifting up and down through gears without grinding of any sort. if the clutch is ok on it (being an 03) i assume its still touchy , ull be ok

Dear Pravin,

Always check for the oil level before you start for the first time during the day. If you can just shake the bike you'll know how thick or light the oil is. The more lighter, you'll have to change faster. Also check for color. Oil can be maroon/red/dark green/etc. depending on brand. If its really black, change it fast. Dont do top ups. Better drain the entire oil and fill fresh oil.

The oil also acts as a lubricant to the gearbox. If you feel gear shifting is becoming too slippery or too tough, check for the viscousity, as said earlier. Slipping gear shift can also be due to a loose chain. So check for that too.

By the time you finish 1500 kms or 2000kms, its better to change the oil.

It is better to use Castrol Power1 for Pulsar. It prevents overheating and also keeps the engine and gearbox smooth. It also maintains viscousity at high temperatures for better lubrication.

My experience:

I used to put servo and every 900-1000 kms i had to change oil. Now with Castrol, I change only between 1500-2000kms. I'm getting mileage between 50 and 55kms for a litre of unleaded petrol.

Hope this helps in solving your problem.

Have a nice time riding pulsar.

Always wear helmet and drive safely.

620 Transmission Problem


Have you looked at the countershaft sprocket? Also check the chain for kinks... Countershaft sprockets bend and chains stretch or bend side to side, Me thinks you got ^^^^ The gear boxes are almost over built on the 620's It would be hard to damage them. You might also check the belt timing as you might have spit a belt off, Or forced it to hop a tooth. Pulling the timing belt covers is easy. The timing marks are marked on the cases and pullies. Just line them up with motor in top dead center. The older monsters had bad countershaft bearing that would fail. Great way to check for internal damage is to drain the oil and check the pre-screen. Good Luck
